IMPROVEMENT IN'DEvlcEs FOR CLOSING pooRs.

Specicationforming part of Letters Patent No. 5,061 dated April 10, 1847.

.T0 a/ZZ whom t may concern: I

Be it known that I, RICHARD F. STEVENS, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Apparatus for Closing Doors, Gates, and Blinds; andI do hereby declare that the following vis a full,clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification. f

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct two plates A and B, of any con-I venient form and dimensions, having several holes made through them for the passage of screws, by which they (A and B) are-made fast to the door C and casing D. From the center of each plate projects a knob E, having on one side a shallow socket or depression F. I then construct a shaft or rod I-I, of any convenient dimensions, and having: the' ends rounded or pointed. One plate A is then fastened by screws to the door, gate, or blind, having the socket downward. The plate B is then fastened toy the casing D, having its socket upward. When the plates A'and B are thus fastened, the distance between the sockets in each must be the same asl the length of the rod H. The rod H is then placed between the sockets, having its upper end in the socket upon the dooiyga'te, or blind and its lower end in the socket upon the casing. A

The operation of my invention is as follows:

On accountof the oblique or inclined position of the rod H the door is vraised on its hinges while being opened by the'rod H approachin g a line perpendicular with the socket upon the casing, the weight of the door rest' ing upon the sockets and rod.v The door,

gate, or lblind is then closed by its own Weightand the -rod again becmes inclined, as before.

The force by which the door, gate, or blind is closed may bevaried by varying the obliquity or inclination of the rod II when the door is closed. v v

By placing the socket upon the casing ata i point nearer the joint @and b ot' the door than the socket, which is fastened to the door; the rod may be made to become perpendicular at any point desired in opening the door, land afterward operate in an opposite direction and hold the door, gate, or blind open.

The purpose of my invention is thatof raising doors, gates, and blinds upon their hinges v i as they are opened and'afterward closing them,

- and also that of holding them open, if desired,

What I claim as my invention, and desire to secure by Letters Patent, isl The application ot the rod and sockets or fastenings, as described, to doors, gates, and blinds in such a manner that when one socket is fastened to the door, gate, or blind and the other to the casing the rod will stand obliquely across the joint aand b, for the pur-` pose and substantially as described.
